Description

Encircling type expansion rubber block

Technical Field

The utility model relates to the technical field of automobile NVH (noise, vibration and harshness), in particular to an encircling type expansion rubber block.

Background

In order to solve the technical problem of NVH (noise, vibration and sound vibration roughness) systematicness of an automobile body, an expansion rubber block is required to be arranged in an A column of the automobile body in white, and a partition sealing solution of the expansion rubber block EVA (ethylene vinyl acetate copolymer) is adopted, wherein the EVA is thermoplastic resin formed by high-pressure polymerization of ethylene and vinyl acetate monomers, has a low melting point and good elasticity, and is a high-rate foaming material easily prepared by a cross-linking foaming technology). The expansion rubber block partition product is composed of a framework and foam rubber EVA, and noise is blocked outside a vehicle body through a grading partition, sound absorption, noise reduction and sealing mode, so that the NVH performance of the whole vehicle is finally greatly improved. The improvement of the safety requirement is always researched at present, the reinforcing plate of the B column reinforcing plate becomes standard matching, and the existence of the reinforcing plate enables the cross section to be different from the common cross section, and the rubber block cannot be normally arranged for plugging, so that a novel surrounding type expansion rubber block product is urgently needed, the assembly can be met, and the requirements for plugging the cross section can be met

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of overcoming the defects in the prior art and provides an encircling type expansion rubber block.

The utility model is realized by the following technical scheme: the utility model provides an embrace type inflation and glue piece, its characterized in that glues a main part, bending plate and fixed buckle including the inflation, the inflation is glued a main part and is included fixed skeleton and EVA, the EVA cladding is on the surface of fixed skeleton, bending plate and fixed skeleton integrated into one piece just are located the both sides of fixed skeleton, be equipped with the depressed part that the bending plate of being convenient for carries out the buckling on the bending plate, fixed buckle passes through the connecting plate and links to each other with the surface of fixed skeleton.

According to the above technical scheme, preferably, the bending plate is obliquely arranged in a straight state, the tail end of the bending plate extends towards the inner side of the fixed framework, and the concave part bends inwards when bending.

According to above-mentioned technical scheme, preferably, the connecting plate is the triangle-shaped connecting plate, and fixed buckle sets up with the tip of connecting plate is perpendicular.

The utility model has the beneficial effects that: through setting up the technical problem that can't arrange the expansion and glue the piece when the effectual solution has the panel beating turn-ups, under the prerequisite that effectively improves front seat passenger's sense organ impression, shutoff demand when having the panel beating turn-ups has been solved.

Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figures, the utility model provides an encircling type expansion rubber block, which is characterized by comprising an expansion rubber block main body, a bending plate 1 and a fixed buckle 2, wherein the expansion rubber block main body comprises a fixed framework 3 and EVA4, the EVA4 is coated on the surface of the fixed framework 1, the bending plate 1 and the fixed framework 3 are integrally formed and are positioned at two sides of the fixed framework 3, a concave part 5 convenient for bending the bending plate 1 is arranged on the bending plate 1, and the fixed buckle 2 is connected with the surface of the fixed framework 1 through a connecting plate 6.

According to the above embodiment, it is preferable that the bending plates 1 are obliquely arranged in a flat state and the distal ends of the bending plates 1 extend toward the inside of the fixing bobbin 3, and the concave portions 5 are bent inward when being bent.

According to the above embodiment, preferably, the connecting plate 6 is a triangular connecting plate, and the fixing buckle 2 is vertically arranged with the end part of the connecting plate 6, so that the fixing buckle is conveniently connected with the automobile sheet metal.

The working principle of the utility model is as follows: when the product is developed, the product is encircled to be in a straight state, so that the molding is convenient, and when clients are provided, the rubber blocks are packaged by workers of a workshop assembly line and sent to a base for loading; when this part is welding the loading workshop, the workman exerts hard through the installation direction, and when skeleton and panel beating installation, the depressed part atress on the bending plate is buckled for fixed skeleton more laminates the panel beating, toasts through the application, the totally enclosed cavity.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
